Abstract

FIELD: metallurgy.
SUBSTANCE: invention can be used in metallurgy of noble metals, including decontamination of waste cyanide solutions formed in extraction of gold from ledge ore. Proposed method comprises addition of waste cyanide solutions of iron compounds (2+) and processing by high voltage electric pulses at specific power rate of not over 100 kJ/mol. Compounds of iron (2+) represent pyrite in amount of 10-100 kg per 1 ton of solution. Obtained mix of decontaminated solution and pyrite is fed after electric pulse processing for flotation of gold-bearing sulphide ore.
EFFECT: electric power saving, lower gold losses with wastes.
